Fedora 30 running Wayland, with two external monitors or using the laptops own screen.
root-6.16.00-3.fc30.x86_64
kernel-5.0.11-300.fc30.x86_64
glx-utils-8.4.0-3.20181118git1830dcb.fc30.x86_64
Description
Any root session crashes when it attempts to open a TCanvas. e.g.
>root -l
Applying ATLAS style settings...
root [0] TCanvas * c = new TCanvas("hello","hello",800,600);
Error in <RootX11ErrorHandler>: GLXBadContext (XID: 41943418, XREQ: 150)
[xcb] Unknown sequence number while processing queue
[xcb] Most likely this is a multi-threaded client and XInitThreads has not been called
[xcb] Aborting, sorry about that.
root.exe: xcb_io.c:263: poll_for_event: Assertion `!xcb_xlib_threads_sequence_lost' failed.
This may well be the first time I ran root since upgrading to Fedora 30.
